The Wallace O14 Ageing Chamber  ages rubber in accordance with international testing standards. In conjunction with the Rapid Plastimeter, high efficiency cutter and traceability fixture, it ensures maximum productivity when determining the Plasticity Retention Index (PRI) of raw natural rubbers.

Housed in a robust steel case, the O14 features an aluminium block with four chambers that carry the drawer units and sample dishes. Heater elements are wrapped around the block and high quality insulation inside the case minimises heat loss.
An air pump with filter, which provides pre-heated air to the chambers, is located on the rear panel for easy service access.
Test samples are placed on round foil dishes, which locate in recesses in the drawer units.

When a drawer is pushed in, a timing sequence starts only for that chamber.

As the 30 minute ageing process ends, by changing colour, the light next to the drawer reminds the operator when to remove the sample. If the ageing period is exceeded, the light changes to red indicating that the samples should be discarded.
A temperature of 140^oC (required by the standard) is maintained by a PID Controller, which continuously displays the chamber temperature.

The O14 is protected by a warning system, which is initiated if the correct temperature is exceeded by more than 10^oC.
